Kynar or Kynar 500® is not a finished paint. It is a trade name for PVDF (polyvinylidene fluoride) resin, as is Hylar 5000® also a trade name.
PVDF resin is the raw material used by licensed formulators to manufacture PVDF based coatings. When formulated into a coating composition, the paint contains a minimum of 70% by weight of Kynar 500 resin to manufacture a 70% PVDF resin based coating, that meets the highest performance criteria of AAMA – 2605.
PPG manufactures Duranar®, Valspar manufactures Fluropon®, and Akzo Nobel manufactures Trinar® – all are examples of 70% PVDF coatings that utilize the Kynar 500 and / or Hylar 5000 resin.
The key to a products performance is the resin chemistry. For the ultimate long-term durability, time has shown that PVDF resin is the one to choose. Other coating resins include acrylic, polyester, silicone polyester and urethane.
Why Specify Kynar 500?
To be both functional and decorative, metal must be coated with a finish that beautifies with color and doesn’t chalk; that won’t lose its color and sheen; that won’t pit, chip, or age before its time. No other coating system withstands the rigors of nature and time like those
based on Kynar 500® resins. This high-performance fluoropolymer resin, with its extraordinary capability to retain color and gloss, keeps painted metal looking
vibrant and appealing.
